' SEEET-METAL ROOFING.

Speciflcation of Letters Pateit.

Patented Sept. 24, 1912.

Application filed January 14, 1911.- Serial No. 602,546.

To all whom it may concern:

Be it known that I, JOHN L. FAULHABER, a citizen of the United States, residing at Elwood in the county 'of Madison and State of Indiana, have invented certain new and water which may be taken up by capillary attraction at the joints of the Sheets constituting or going to make up the roof. This Object together with other objects readily apparent to those skilled in the art, I attain by the construction illustrated in the accompanying drawing, although my invention may be embodied in a variety of other mechanical forms, the construction illustrated being chosen by Way of example.

In the accompanying drawing-Figure 1 is a perspective' view showing portions of two Sheets of roofing showing said Sheets in proper relative position with reference to each other. Fig. 2 is a transver-se or horizontal section showing two Sheets properly lapped one upon the other, except that the lapped portions of the sheet are .shown slightly spaced from each other.

Similar numerals of reference 'indicate corresponding parts in all the figures of the drawing.

In the accompanying drawing, '1 represents the roofing Sheets which are corrugated long'itudinally, the corrugations being formed of practically the same size and shape in each Sheet so that one or more corrugations of the upper sheet may rest upon one or more oorrugations of the lower Sheet by which arrangement and location joints are produced, which joints are ordinary .lapped joints;

It will be unders'tood that the corrugations of the' Sheets are to be parallel withthe pitch of the roof, that is to say the corrugations are to extend lengthcomb or upper part of the roof. The Sheets are secured to theroof boards or other supports for the Sheets in the usual manner preferably by nails, the nails being driven through the Sheets at the apei'res of the corrugations. It is wel] understood that dampness, resulting from fog, dew and the like gathers upon the upper surface of metallic roofing so as to produce Water in appreciable quantities. This water, as well as rain water is conveyed'by capillary attract-on between the lapp'ed or joined-portions of the Sheet metal going to make up the roof proper, such water being thus conveyed .to the Sheeting of the roof, thus causing the roof to leak. Fine snow and ice ;also frequently finds its way between the overlapped portions of the Sheets producing Similar trouble.

For the purpose of properly draining all Water that may find its way between the lapped portions or through the scams of the roofing I provide one edge of each 'Sheet with the flange 2, which flange extends upward at substantially right angles to the horizontai plane of the roofing Sheet and of such a height that the flange can be located under one of the corrugations, that is to say under the concaved face of one of the corrugations, said corrugationby reason of its upward curvature provides sufiicient room for the flange 2 'tg lie under the Sheet which is lapped upon or over an adjacent Sheet. The flange 2 is for`the purpose of checkin'g the flow of water which finds ts way through the lapped portion or a seam of adjacent Sheets and convey'ng the water to the* eavesof the roof.

It will be unde'rstood that the flangewill produce what might be termed a channel or trough of sufiicient size to properly conduct' all the water and dampness carried by capllary attraction under-the upper lapped portion ofthe Sheets.

The flange or its equivalent formed upon `l the lateral edge of each of the roofing Sheets provides adrainage groove of simple construction without materially increasing the expense of the manufacture of the Sheets and at the same time adding little if'any additional labor in roof.

While I have shownand *desc'ribed the ,Sheets goingto make` up the roof as provided placing the Sheets upon the withrounded corrugations it should be understood that I do not desre to be limited to such exact construction. Angular or other corrugations may be substituted for such rounded-corrugations, the essential feature of my invention being that the overlapped lateral edges of the sheets along one definite line are sufiiciently spaced from each other to destroy capillary attraction and produce a drainage groove adapted to carry the water from between the overlapped portions down to thebottom edge of the roof without permitting it to be deposited upon the sheathing beneath the metallic plates.

A portion of the underlapped sheet adjacent the flange 2 is formed flat, which flat portion is located adjacent the fiange :2 and is so formed for the purpose of properly supporting the underlapped portion at the joint and in such a manner that it will not be sprung or bent.

By rcasonof the fact that the body of each sheet is provided with a series of longitudinal corrugations. extending to the side edge opposite the flange 2, the said sheets may be longitudinally cut when desired along any of the corrugations in the body of the sheet, and when so cut said cut edge of the sheet will overlie the flange 2, as shown in the drawings and herein above described, it being thus possible to arrange the roong to cover a roof of any size whether same is of such a length as to be covered by a plurality of standard Sheets or not. In this way it will be found very convenient to apply the roofing herein described in cases where other roofing could not be used so advantageously.

Having fully described my invention what I clain as new and desire to secure by Letters Patent, is-

1. In roofing of the character described a substantially rectangular sheet of metal provided at one side edge with an integral upturned flange standing substantially at right-angles to the plane of the sheet, a plain portion adjacent said upturned flange, and corrugations in the body of said sheet extending parallel to said flange and arranged in series from said plain portion to the oppositc side edge of the sheet.

2. Sheet metal roofing consisting of aplurality of substantially rectangular Sheets of metal with over-lapping edges, each sheet provided in its body portion with longitudinal corrugations arranged parallel to each other and to the side edges of the sheet, said corrugations extending in transverse series to one of said side edges, the other side edge of the sheet being plain and having a por tion turned into vertical position with reference to the general plane of the sheet, and a plain portion arranged intermediate said vertically disposed portion and said corrugations, and the corrugated edge of one sheet over-lapping the plain edge of the other sheet, said plain intermediate portion and said vertical portion of one sheet With the over-lapping corrugated edge of the other sheet forming an air space adapted to interrupt capillary attraction.

In testimony that I claim the above, I have hereunto subscribed my name in the presence of two witnesses.

JOHN L. FAULHABER.
